The one or more pairs of tightening parts tighten the bottom part and the side surface supporting part to be in close contact with the foot of the user.

TECHNICAL FIELD

An exemplary embodiment of the present disclosure relates to a shoe and, more particularly, to a shoe provided with a liner having an improved function.

BACKGROUND

A shoe serves to protect a foot of a human, and the shoe protects the foot from an exterior environment when the human walks or runs.

In general, the shoe includes an upper, a sole, and a liner. The upper surrounds a top of a foot of a user, and the sole is attached to a lower portion of the upper, comes into contact with the ground, and absorbs impact. The liner is disposed on the sole so as to be in contact with a bottom of the foot of the user, and protects the bottom of the foot of the user.

However, because a size and a shape of the foot differ from user to user, there is still a space between the liner of the shoe and the foot of the user even though the liner of the shoe is ergonomically designed.

This space not only adversely affects wearing comfort of the shoe, but also causes deterioration in exercise capacity of the user.

In particular, when the user wears the shoe, and repeatedly changes a direction while walking or running, or repeatedly and rapidly stops, friction occurs in the space between the foot of the user and the liner of the shoe. As a result, there is a problem in that the user is injured such as having a blister on the foot of the user.

Hereinafter, a shoe 101 according to a first exemplary embodiment of the present disclosure will be described with reference to FIGS. 1 and 2.

As illustrated in FIGS. 1 and 2, the shoe 101 includes an upper 10, a liner 20, and a sole 30.

The upper 10 surrounds and protects the whole or one part of a foot of a user. In the first exemplary embodiment of the present disclosure, the upper 10 may have various shapes, and may surround and protect the ankle of the user as well as the foot.

In addition, in the first exemplary embodiment of the present disclosure, the upper 10 includes opening portions 19 that are formed at a portion of a top of the foot or at a portion of the ankle.

The sole 30 is coupled to a lower portion of the upper 10, and comes into contact with the ground. The sole 30 absorbs impact applied from the ground when the user walks or runs. For example, the sole 30 may include a middle sole which includes an elastic body for absorbing impact, and an outer sole which protects the middle sole and comes into direct contact with the ground.

The liner 20 is disposed on the sole 30. Specifically, in the first exemplary embodiment of the present disclosure, the liner 20 includes a bottom part 21, side surface supporting parts 22, and tightening parts 23.

The bottom part 21 is disposed on the sole 30, and comes into contact with a bottom of the foot of the user.

The side surface supporting parts 22 are extended from a side edge of the bottom part 21, and partially surround a side surface of the foot of the user. The side surface supporting parts 22 are formed at both sides of the foot of the user, respectively, and one or more pairs of side surface supporting parts may be provided. Further, the side surface supporting parts 22 are disposed inside the upper 10.

In FIG. 2, the side surface supporting parts 22 surround a middle portion of the foot of the user, but the first exemplary embodiment of the present disclosure is not limited thereto. That is, one or more pairs of side surface supporting parts 22 may surround one or more side surfaces of a front portion, a middle portion, and a rear portion of the foot of the user.

Specifically, in the first exemplary embodiment of the present disclosure, a portion where the side surface supporting part 22 is formed may vary according to the main purpose of use of the shoe 101. For example, the side surface supporting part 22 may be formed at a position that corresponds to a front portion of the foot in the case of a tennis shoe with which the user changes a direction mainly using the front portion of the foot, the side surface supporting part 22 may be formed at a position that corresponds to a middle portion of the foot in the case of a running shoe, or the side surface supporting part 22 may be formed at a rear portion of the foot in the case of a basketball shoe.

The tightening parts 23 are formed at end portions of the one or more pairs of side surface supporting parts 22, respectively. That is, one or more pairs of tightening parts 23 are provided. Further, the tightening parts 23 protrude to the outside of the upper 10 through the opening portions 19 of the upper 10. The tightening parts 23 serve to tighten the bottom part 21 and the side surface supporting part 22 to be in close contact with the foot of the user.

In the first exemplary embodiment of the present disclosure, the tightening part 23 includes tightening main bodies 231 which protrude to the outside of the upper 10, coupling holes 232 which are formed in the tightening main bodies 231, and a shoe strap 233 which is fitted into the coupling holes 232. That is, when the shoe strap 233 included in the one or more pairs of tightening parts 23 is tied, the side surface supporting parts 22 and the bottom part 21 are tightened so as to be in close contact with the foot of the user by the one or more pairs of tightening parts 23 positioned at both sides of the foot of the user, respectively.

In addition, in the first exemplary embodiment of the present disclosure, one or more pairs of tightening parts 23 may tighten to the top of the foot of the user.

In addition, in the first exemplary embodiment of the present disclosure, the liner 20 may be made using one or more materials of synthetic resin, natural rubber, leather, and fabric. That is, the liner 20 may be made of one of synthetic resin, natural rubber, leather, and fabric, or a combination thereof.

For example, a portion of the bottom part 21 of the liner 20 which faces the sole 30 may be made of synthetic resin, and a portion of the bottom part 21 of the liner 20 which faces the foot of the user may be made of fabric or leather. In addition, the side surface supporting part 22 and the tightening main body 231 of the tightening part 23 may be made of synthetic resin or fabric, and the shoe strap 233 of the tightening part 23 may be made of fabric. In addition, the liner 20 may be made of various combinations of materials in addition to the aforementioned combination.

By the aforementioned configuration, the shoe 101 according to the first exemplary embodiment of the present disclosure may prevent an injury, and may improve wearing comfort and an exercise capacity.

Specifically, when the user wears the shoe 101 according to the first exemplary embodiment of the present disclosure and tightens the tightening part 20 in accordance with a size of the foot, the bottom part 21 and the side surface supporting part 22 of the liner 20 come into close contact with the foot of the user, and a vacant space between the foot of the user and the liner 20 is minimized That is, even though the shape of the foot slightly varies from user to user, the shoe 101 according to the first exemplary embodiment of the present disclosure may minimize the vacant space between the foot and the liner 20 regardless of the shape of the foot.

As described above, in the first exemplary embodiment of the present disclosure, when the shoe strap 233 is tightened, the liner 20 supports the foot while having a shape closest to the shape of the foot of the user, thereby improving wearing comfort and unity of the shoe 101.

In addition, in the first exemplary embodiment of the present disclosure, the liner 20 supports the foot while surrounding and coming into close contact with the side surface of the foot and the top of the foot as well as the bottom of the foot of the user, thereby dispersing the load and reducing a degree of fatigue of the foot when the user performs comparatively strenuous exercise such as a rapid change in direction, a sudden stop, and rapid acceleration.

In addition, according to the first exemplary embodiment of the present disclosure, sliding of the foot of the user on the liner 20 may be minimized, thereby preventing an injury such as a blister on the foot from occurring due to friction between the foot of the user and the liner 20.

Hereinafter, a second exemplary embodiment of the present disclosure will be described with reference to FIG. 3.

As illustrated in FIG. 3, a tightening part 23 of a liner 20, which is used in a shoe according to the second exemplary embodiment of the present disclosure, includes tightening main bodies 231 which protrude to the outside of an upper 10, and Velcro® coupling portions 234 which are formed on one surface of the tightening main bodies 231.

In addition, the Velcro® coupling portion 234 may include various types of Velcro®-like materials that are publicly known to those skilled in the art.

By the aforementioned configuration, the shoe according to the second exemplary embodiment of the present disclosure prevents an injury, improves wearing comfort and an exercise capacity, and allows the user to easily tighten the liner and wear and take off the shoe.

Hereinafter, a third exemplary embodiment of the present disclosure will be described with reference to FIG. 4.

As illustrated in FIG. 4, any one tightening part 23 of one or more pairs of tightening parts 23 of a liner 20, which is used in a shoe according to the third exemplary embodiment of the present disclosure, includes a first tightening main body 2311, and a fitting ring 235 formed at an end portion of the first tightening main body 2311. Further, the other tightening part 23 of one or more pairs of tightening parts 23 includes a second tightening main body 2312 which has a length relatively longer than a length of the first tightening main body 2311, and is fitted into the fitting ring 235.

That is, the second tightening main body 2312 is fitted into the fitting ring 235 installed at the end portion of the first tightening main body 2311 so as to tighten the side surface supporting part 22 and the bottom part 21 of the liner 20.

By the aforementioned configuration, the shoe according to the third exemplary embodiment of the present disclosure prevents an injury, improves wearing comfort and an exercise capacity, and allows the user to easily tighten the liner and wear and take off the shoe.

Hereinafter, a fourth exemplary embodiment of the present disclosure will be described with reference to FIG. 5.

As illustrated in FIG. 5, a side surface supporting part 22, which is used in a shoe according to the fourth exemplary embodiment of the present disclosure, is formed at a portion that corresponds to a rear portion of the foot of the user, and a tightening part 23 surrounds and tightens to the ankle of the user.

In this case, like the first exemplary embodiment of the present disclosure, the tightening part 23 includes tightening main bodies 231, coupling holes 232 which are formed in the tightening main bodies 231, and a shoe strap 233 which is fitted into the coupling holes 232.

By the aforementioned configuration, the shoe according to the fourth exemplary embodiment of the present disclosure prevents an injury, improves wearing comfort and an exercise capacity, and particularly, may be effectively applied to the shoe that is suitable for an exercise such as a basketball game.

Hereinafter, a fifth exemplary embodiment of the present disclosure will be described with reference to FIG. 6.

As illustrated in FIG. 6, a side surface supporting part 22, which is used in a shoe according to the fifth exemplary embodiment of the present disclosure, is also formed at a portion that corresponds to a rear portion of the foot of the user, and a tightening part 23 surrounds and tightens to the ankle of the user.

In this case, like the second exemplary embodiment, the tightening part 23 includes tightening main bodies 231, and Velcro® coupling portions 234 which are formed on one surface of the tightening main bodies 231.

By the aforementioned configuration, the shoe according to the fourth exemplary embodiment of the present disclosure prevents an injury, improves wearing comfort and an exercise capacity, particularly, may be effectively applied to the shoe that is suitable for an exercise such as a basketball game, and may allow the user to easily wear and take off the shoe.

Hereinafter, an operational effect of the present disclosure will be specifically described while comparing an experimental example according to the first exemplary embodiment of the present disclosure with a comparative example with reference to FIGS. 7 and 8.

FIG. 7 illustrates the comparative example according to a general shoe, and FIG. 8 illustrates the experimental example according to the first exemplary embodiment of the present disclosure.

As illustrated in FIG. 7, in the case of the comparative example, when the user rapidly changes a direction, the user's foot inside the shoe slides and leans to one side in the vacant space. As a result, friction occurs between the foot and a liner 200. This friction not only degrades an exercise capacity of the user, but also causes an injury such as a blister on the foot.

In FIG. 7, reference numeral 100 indicates the upper, and reference numeral 300 indicates the sole.

In contrast, as illustrated in FIG. 8, in the case of the experimental example, since the bottom part 21 and the side surface supporting part 22 of the liner 20 are in close contact with the foot of the user while having unity by the tightening part (not illustrated in FIG. 8), friction between the liner 20 and the foot is minimized Instead, friction occurs between the liner 20 and the sole 30 of the shoe, but the liner 20 protects the foot of the user, and prevents the foot from being injured due to the friction.
